Building Instructions Sub12 DSP

The assembly of the cabinet

The Sub 12 consists of 6 external panels, one separating panel and 4 internal bracing panels which reduce the intrinsic resonance of the wooden cabinet. All 10 panels should be glued together and attached with screws (if required). Afterwards - or before - 4 openings for
- the bass driver,
- the amplifier module and its panel (on the baffle),
- the bass reflex port, underneath
should be cut.

Then the feet should be mounted. The distance between cabinet and floor tunes the loudspeaker, since this represents an extension of the bass reflex tube. Should the speaker be positioned close to a corner, the feet may be shortened by 5 mm.

Bass reflex tube tuning

Sub 12 von unten To be able to tune the loudspeaker accurately to low frequencies, a long bass reflex tube is needed. This can be achieved by connecting the 2 supplied tubes HP 100. We suggest to fit the first tube from below; the second one be should attached (textile sticky tape, plastic glue,...) to the first tube by using the bass driver opening.

The assembled bass reflex tube should then be wrapped once with needle felt and secured with cable fasteners.

The left over needle felt should be placed around the bass reflex tube on the bottom panel of the cabinet. The remaining part is relatively easy: the amplifier module needs to be mounted after the cabeling for the woofer and for the panel has been fixed.

Than the panel shoul dbe mounted on the front side of the woofer.

Afterwards the bass driver is connected and mounted since it is a lot easier to connect the bass driver when it's not mounted yet.

The bass driver should be attached last.

The Omnes Audio DPA 200' bass response is tuneable. We suggest, however, to try the neutral default setting first. For lowest bass and highest sound pressure level this seems to us the best setting.

Operation

The subwoofer needs to be connected to the amplifier (via cinch cable to the pre-out terminal or with speaker cable to the (satellite) speakers and the mains cable to the wall plug....
